Disclosed is an improved spear head overshot. The spear head overshot is particularly useful as part of a cable-guided fishing assembly. The spear head overshot essentially comprises one or more pivot lugs, the pivot lugs comprising jaw sections and release point sections, an actuator slide, a wave spring, a pivot mandrel, a screw attached to the pivot mandrel, and a compression spring threaded over the screw. In operation, a spear head is inserted into the spear head overshot until the spear head passes the jaw sections of the pivot lugs, at which time the spear head is locked into place. To release the spear head, the release point sections of the pivot lugs are manually forced inward. Simultaneously, the jaw sections of the pivot lugs are forced outward, thereby allowing the spear head to be removed from the spear head overshot. In a cable-guided fishing operation, this process can be repeated as often as necessary.
